摘　　要：食品二氧化碳是碳酸类饮料重要的食品添加剂;在产品的生产过程中,质量受各种因素影响;如何在生产过程中高效控制产品质量是企业质量和效益平衡的重要因素;针对这种情况,设计了实时在线质量控制系统的硬件和软件方案;用阀切换气体来源,气体进入预处理后,再进入在线分析仪器中;分析后的数据由下位机采集,通过上位机软件分析处理并发送给集散控制系统,对设定值和反馈值比较,计算并调节参数,指挥和控制系统,调度生产运行;经过实验运行,结果表明,该系统在质量设定阈值内用PID控制,超过阈值用Fuzzy-PID复合控制;工艺参数调节稳定可靠;当质量超出设定的报警参数后,系统能及时切换输出流路,防止不合格产品流入食品储罐,保证了产品的食品级质量,与此同时切换生产线,并启动再生进程;利用此系统可实现食品级二氧化碳生产的在线质量控制及质量溯源追踪。Food carbon dioxide is an important food additive for carbonated beverages.In the production process of products,the quality is affected by various factors.How to efficiently control the product quality in the production process is an important factor in the balance of quality and benefit for enterprise.In view of this situation,the hardware and software scheme of real-time online quality control system is designed.The gas source is switched with a valve,and the gas enters the online analysis instrument after the pretreatment.The analyzed data is collected by the lower computer,which is analyzed and processed by the upper computer software and sent to the distributed control system.Compared the set value with the feedback value,the parameters are calculated and adjusted to command and control system to the production and operation of schedules.After the experimental operation,the results show that the system is controlled by PID within the quality setting threshold and Fuzzy-PID compound control over the threshold.The adjustment of process parameters is stable and reliable.When the quality exceeds the set alarm parameters,the system can switch the output flow path in time to prevent unqualified products from flowing into the food storage tank,which ensures the food quality of the product.At the same time,the system can switch the production line and start the regeneration process.Using this system,the online quality control and quality traceability of food grade carbon dioxide production can be realized.
